[cairo] A patch to detect CTFont API availability (Re: [PATCH 2/3] Update README with new minimum MacOSX requirements)

[suzuki toshiya]

Hi,

Here I propose a patch to restore the support of Mac OS X 10.4
support, which detects the CTFont availability by configure,
following to the design by Ryan Schmidt
http://lists.cairographics.org/archives/cairo/2015-February/025959.html

I don't think the change is too complex to drop Mac OS X 10.4
support... How do you think of?

Regards,
mpsuzuki
